Description

BACKGROUND
• An access point of a network may provide network coverage to allow one or more wireless devices to communicate via the network. For example, a wireless device (e.g., an Internet of Things device or a user device) may communicate with a destination device (e.g., a server, a control device, or a monitoring device) via the network. The wireless device may determine that a signal strength associated with the network fails to satisfy a threshold, and may duplicate a portion of a transmission to reduce a likelihood that the portion of the transmission will fail to be received by a base station as a result of poor network coverage associated with the signal strength failing to satisfy the threshold. For example, the wireless device may transmit multiple copies of a packet to increase a likelihood that at least one copy of the packet is received by the base station and provided to the destination device.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
• The following detailed description of example implementations refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.
• A signal strength associated with a network may vary based on a location of a wireless device relative to an access point (e.g., a base station). For example, a signal strength associated with a network may be relatively strong (e.g., the signal strength may satisfy a threshold) near a base station and relatively weak (e.g., the signal strength may fail to satisfy the threshold) farther from the base station. Similarly, the network may be associated with a relatively weak signal strength at a remote location, inside a building, or the like. The wireless device may experience dropped calls, lost packets, or ineffective attempts to connect to the network when utilizing a network for which network coverage is poor, such as a network for which the signal strength is relatively weak, a network to which a threshold quantity of wireless devices are connected, a network associated with a congestion condition, or the like. For example, when the wireless device is being utilized at a remote location, the wireless device may transmit network traffic to the base station, but the base station may fail to receive the network traffic. Similarly, when the wireless device is being utilized at a particular location, such as a stadium, and a threshold quantity of other wireless devices are also being utilized at the particular location, packets transmitted by the wireless device may be dropped.
• When the wireless device determines that the network coverage is poor, such as when a signal strength associated with the network fails to satisfy a threshold, the wireless device may utilize a coverage enhancement mode. For example, the wireless device may cause one or more duplicates of a transmission to be transmitted. In this case, the wireless device may transmit multiple copies of each packet of a set of packets of the transmission. In this way, the wireless device may increase a likelihood that at least one copy of each packet of the set of packets of the transmission is received relative to when the wireless device is not utilizing a coverage enhancement mode. However, when multiple wireless devices each transmit multiple copies of multiple transmissions, the network may enter a congestion condition or may have a congestion condition exacerbated. Moreover, a particular wireless device may utilize excess network resources of the network, thereby negatively impacting user experience, wireless device performance, network performance, or the like for one or more other wireless devices connected to the network or attempting to connect to the network. Furthermore, a base station may be required to utilize excess processing resources to process the multiple copies of the multiple transmissions.
• Implementations, described herein, may perform network device based control of the coverage enhancement mode. Based on centralizing control of the coverage enhancement mode, the network device reduces a likelihood that an excess quantity of wireless devices utilize the coverage enhancement mode and cause excess network traffic relative to permitting each wireless device to separately determine to use the coverage enhancement mode regardless of overall network conditions. Moreover, the network device may utilize prioritization information regarding a set of wireless devices connected to a network, thereby increasing a likelihood that a high priority wireless device, such as a wireless device utilized by emergency management personnel, is able to transmit information via the network. As a result, the wireless device improves network performance relative to permitting distributed control of the coverage enhancement mode by each wireless device of the network. Furthermore, the network device reduces a utilization of processing resources by the base station to process the network traffic relative to permitting excess quantities of duplicate packets to be transmitted to the base station for processing.
• FIG. 1 is a diagram of an overview of anexample implementation100 described herein. As shown inFIG. 1,example implementation100 may include one or more wireless devices, a base station, and a network device.
• As further shown inFIG. 1, and byreference number110, the network device may determine a level of coverage enhancement for a coverage enhancement mode based on information associated with the one or more wireless devices. For example, based on receiving a request to enter the coverage enhancement mode from the one or more wireless devices, the network device may determine a class of service for the one or more wireless devices, and may determine a particular level of coverage enhancement for the one or more wireless devices based on the class of service. In this case, the network device may determine a relatively high level of coverage enhancement (e.g., a relatively large quantity of duplicates of a transmission) for a first wireless device with a relatively high class of service (e.g., a network-connected smoke detector) and a relatively low level of coverage enhancement (e.g., a relatively small quantity of duplicates of a transmission) for a second wireless device with a relatively low level class of service (e.g., a network-connected parking meter). In another example, the network device may determine that a third wireless device is not to utilize the coverage enhancement mode based on the third wireless device being associated with a class of service lower than the class of service of the second wireless device.
• Additionally, or alternatively, the network device may determine the level of coverage enhancement for the one or more wireless devices based on determining a network measurement associated with the one or more wireless devices. For example, the network device may receive information identifying a set of measurements associated with the one or more wireless devices, such as a set of signal strength measurements, a set of reference signal received power (RSRP) measurements, a set of reference signal received quality (RSRQ) measurements, a set of received signal code power (RSCP) measurement, a set of bit error rate (BER) measurements, or the like. In this case, the network device may determine the level of coverage enhancement for each wireless device based on the set of measurements.
• Additionally, or alternatively, the network device may determine the level of coverage enhancement for the one or more wireless devices based on another metric, such as a quantity of wireless devices connected to the base station, an amount of network traffic being received by the base station, or the like. For example, when the amount of network traffic satisfies a congestion threshold, the network device may determine a relatively low level of coverage enhancement to reduce a utilization of processing resources by the base station (e.g., to process duplicate packets transmitted by the one or more wireless devices), thereby avoiding overloading the base station. Similarly, when the amount of network traffic does not satisfy the congestion threshold, the network device may determine a relatively high level of coverage enhancement to reduce a likelihood that a transmission fails to be correctly received by the base station.
• As shown byreference number120, based on determining the level of coverage enhancement for the coverage enhancement mode for the one or more wireless devices, the network device may provide information, to the one or more wireless devices, identifying the level of coverage enhancement for the coverage enhancement mode. For example, the network device may transmit information identifying a coverage enhancement parameter to cause the one or more wireless devices to utilize one or more determined levels of coverage enhancement. In this case, the coverage enhancement parameter may indicate a level of coverage enhancement, which may correspond to a particular quantity of duplicate packets to be transmitted.
• As shown byreference number130, based on receiving information identifying the level of coverage enhancement (e.g., the coverage enhancement parameter), the one or more wireless devices may activate the coverage enhancement mode and/or may utilize the level of coverage enhancement when transmitting network traffic. For example, a first wireless device may activate the coverage enhancement mode and transmit a relatively large quantity of copies of a packet (e.g., 10 copies, 100 copies, or 1000 copies) when utilizing a relatively high level of coverage enhancement. Similarly, a second wireless device may activate the coverage enhancement mode and may transmit a relatively small quantity of copies of a packet (e.g., 2 copies, 3 copies, or 4 copies) when utilizing a relatively low level of coverage enhancement.
• As shown byreference number140, the base station and/or network device may receive network traffic from the one or more wireless devices based on the one or more wireless devices utilizing the coverage enhancement mode. For example, the base station may receive multiple copies of a packet from a wireless device, and may cause a particular copy to be directed toward a destination device.
• In this way, by centralizing the level of coverage enhancement for the one or more wireless devices rather than permitting the one or more wireless devices to perform a distributed determination of the level of coverage enhancement, the network device selectively prioritizes the network traffic, thereby improving the management of network traffic. Moreover, the wireless device reduces a likelihood of excess network congestion being caused and/or excess processing resources of the base station being utilized relative to permitting the one or more wireless devices to determine the level of coverage enhancement. Furthermore, the network device permits network resources to be allocated to the one or more wireless devices in the coverage area based on a prioritization of the one or more wireless devices, thereby improving network performance, wireless device performance, user experience, or the like relative to another technique for determining a level of coverage enhancement that does not account for the prioritization of the one or more wireless devices.

For example,network device230 may detect the trigger to configure the coverage enhancement mode. In some implementations,network device230 may detect the trigger to configure the coverage enhancement mode based on receiving information indicating that transmitted network traffic was not properly received. For example,network device230 may receive information fromwireless device205,base station210, or the like indicating that one or more transmitted packets were not received, and may determine that a level of coverage enhancement is to be determined forwireless device205.

• In some implementations,network device230 may detect the trigger to configure the coverage enhancement mode based on detecting a threshold amount of network traffic associated withbase station210. For example, whennetwork device230 detects that the quantity of network traffic satisfies a threshold,network device230 may configure the coverage enhancement mode of one or morewireless devices205 in a coverage area ofbase station210 to reduce the quantity of transmitted packet duplicates. In this way,network device230 may reduce network congestion, may reduce a utilization of computing resources bybase station210, or the like. Additionally, or alternatively,network device230 may be triggered to configure the coverage enhancement mode based on determining that a threshold quantity ofwireless devices205 are associated with the coverage area of base station210 (e.g., that a threshold quantity ofwireless devices205 are within the coverage area, are served bybase station210, or the like).
• In some implementations,network device230 may detect the trigger to configure the coverage enhancement mode based on information identifying a network measurement received from and/or measured bywireless device205. For example, whennetwork device230 receives information indicating that a signal strength, measured bywireless device205, satisfies a threshold (e.g., a detected received signal strength or a determined transmission signal strength),network device230 may determine to configure the coverage enhancement mode.

• As further shown inFIG. 4,process400 may include determining priority information associated with one or morewireless devices205 connected to a network based on detecting the trigger to configure the coverage enhancement mode (block420). For example,network device230 may determine priority information, associated with one or morewireless devices205 connected to the network, based on detecting the trigger to configure the coverage enhancement mode for the one or morewireless devices205.

• In some implementations,network device230 may determine the class of service for the one or morewireless devices205 based on detecting the trigger to configure the coverage enhancement mode for the one or morewireless devices205. For example, based on detecting the trigger,network device230 may request subscriber information regarding the one or more wireless devices205 (e.g., from HSS235), and may receive information identifying the subscriber information for the one or morewireless devices205. The subscriber information may indicate a class of server forwireless device205. Additionally, or alternatively,network device230 may obtain stored subscriber information from a data structure ofnetwork device230, based on querying the one or morewireless devices205, or the like.
• In some implementations,network device230 may determine a set of network measurements regarding the one or morewireless devices205 based on detecting the trigger to configure the coverage enhancement mode for the one or more wireless devices. For example,network device230 may transmit, to the one or morewireless devices205, a network measurement request, and may receive information identifying a signal strength measurement, an RSRP measurement, an RSRQ measurement, a BER measurement, or the like from the one or morewireless devices205. In this case,network device230 may causewireless device205 to perform a new measurement, to obtain stored information identifying a previously performed measurement, or the like.
• As further shown inFIG. 4,process400 may include determining a level of coverage enhancement based on determining the priority information (block430). For example,network device230 may determine the level of coverage enhancement for the one or morewireless devices205 based on determining the priority information associated with the one or morewireless devices205 connected to the network.
• In some implementations,network device230 may determine the level of coverage enhancement based on subscriber information for the one or morewireless devices205. For example,network device230 may determine one or more levels of coverage enhancement, which correspond to one or more classes of service assigned to the one or morewireless devices205, for one or morewireless devices205.
• In some implementations,network device230 may determine the level of coverage enhancement based on determining one or more network measurements associated with the one or morewireless devices205. For example,network device230 may receive information indicating a first threshold signal strength for afirst wireless device205 and a second threshold signal strength for asecond wireless device205. In this case,network device230 may determine a first level of coverage enhancement for thefirst wireless device205 and a second level of coverage enhancement for thesecond wireless device205.
• In some implementations,network device230 may determine the level of coverage enhancement based on one or more other metrics associated with the network. For example,network device230 may determine the level of coverage enhancement based on a quantity ofwireless devices205 connected to the network. In this case, when the quantity ofwireless devices205 satisfies a threshold,network device230 may determine a relatively low level of coverage enhancement to reduce network congestion and utilization of computing resources bybase station210. Conversely,network device230 may determine a relatively high level of coverage enhancement to increase a likelihood of a successful transmission when the quantity ofwireless devices205 connected to the network fails to satisfy a threshold. Similarly,network device230 may determine the level of coverage enhancement based on a level of network congestion, an amount of network traffic, a utilization of processing resources ofbase station210, or the like.
• In some implementations,network device230 may determine the level of coverage enhancement based on the prioritization of the one or morewireless devices205. For example, when a level of network traffic satisfies a congestion threshold and a signal strength reported by one or morewireless devices205 satisfies a signal strength threshold,network device230 may provide a high level of coverage enhancement towireless devices205 with a high class of service (e.g., emergency management devices) and a relatively low level of coverage enhancement to other wireless devices205 (e.g., non-emergency related devices). In this case,network device230 reduces a likelihood that the packets of data from the one or morewireless devices205 that are associated with responding to an emergency will fail to be received. Moreover,network device230 selectively prioritizes the network traffic, improving the management of network traffic, and reduces a likelihood of excess network congestion relative to permitting eachwireless device205 to independently determine a high level of coverage enhancement based on a relatively poor signal strength. In some implementations,network device230 may allocate a set of network resources based on a prioritization of the one or morewireless devices205.
• In some implementations,network device230 may determine the level of coverage enhancement based on an available battery capacity of one or morewireless devices205. For example, based on receiving information indicating that aparticular wireless device205 is associated with a battery capacity failing to satisfy a threshold,network device230 may select a level of coverage enhancement for one or morewireless devices205 to reduce a utilization of battery resources of theparticular wireless device205. In this way,network device230 reduces a likelihood thatwireless device205 will shut down as a result of a lack of battery resources relative to another technique where coverage enhancement is not selected to maximize battery resources.
• Although implementations are described herein in terms of relatively low coverage enhancement levels and relatively high coverage enhancement levels, other levels of coverage enhancement are possible, such as a continuous set of coverage enhancement levels, a discrete set of coverage enhancement levels, or the like.
• As further shown inFIG. 4,process400 may include providing information to cause the level of coverage enhancement to be implemented (block440). For example,network device230 may provide information, to aparticular wireless device205, to cause the level of coverage enhancement to be implemented by theparticular wireless device205. In this case,network device230 causeswireless device205 to transmit subsequent network traffic utilizing the level of coverage enhancement (e.g., a particular quantity of copies of one or more packets that are transmitted).
• In some implementations,network device230 may transmit information (e.g., an instruction) to causewireless device205 to activate the coverage enhancement mode and utilize a particular level of coverage enhancement. For example, whenwireless device205 is operating in a connected mode, a non-coverage enhancement mode, an idle mode, or the like,network device230 may causewireless device205 to activate the coverage enhancement mode, and transmit network traffic using the coverage enhancement mode. In some implementations,network device230 may transmit information to cause the coverage enhancement mode to remain at a static level. For example,wireless device205 may perform a signal strength measurement and may determine that the signal strength measurement satisfies a threshold associated with a different level of coverage enhancement than the level of coverage enhancement identified bynetwork device230. In this case,wireless device205 may be caused to utilize the level of coverage enhancement identified bynetwork device230 rather than the different level of coverage enhancement corresponding to the signal strength measurement. In this way,network device230 ensures thatwireless device205 utilizes a level of coverage enhancement that does not cause excess network traffic.
• In some implementations,network device230 may store information identifying the level of coverage enhancement to causewireless device205 to utilize the level of coverage enhancement. For example,network device230 may store information via a subscriber profile, associated withwireless device205, that identifies the level of coverage enhancement. In this case,wireless device205 may be caused to utilize the level of coverage enhancement identified by the information stored via the subscriber profile stored bynetwork device230 or another device. Additionally, or alternatively, based on obtaining information identifying a group ofwireless devices205 in a particular coverage area,network device230 may store information via a group of corresponding subscriber profiles for the group ofwireless devices205 to cause the group ofwireless devices205 to utilize the determined level of coverage enhancement. Additionally, or alternatively,network device230 may store information via a set of subscriber profiles to set a level of coverage enhancement for a set ofwireless devices205 associated with multiple coverage areas.
• In this way, by centralizing the level of coverage enhancement for one or morewireless devices205 rather than permitting the one or morewireless devices205 to perform a distributed determination of the level of coverage enhancement,network device230 improves the management of network traffic. Moreover,wireless device205 reduces a likelihood of excess network congestion being caused and/or excess processing resources ofbase station210 being utilized relative to permitting one or morewireless devices205 to determine the level of coverage enhancement. Furthermore,network device230 permits network resources to be allocated to one or morewireless devices205 in the coverage area based on a prioritization of one or morewireless devices205, thereby improving network performance, wireless device performance, user experience, or the like relative to another technique for determining a level of coverage enhancement that does not account for the prioritization of one or morewireless devices205.
• AlthoughFIG. 4 shows example blocks ofprocess400, in some implementations,process400 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted inFIG. 4. Additionally, or alternatively, two or more of the blocks ofprocess400 may be performed in parallel.
• FIGS. 5A-5C are diagrams of anexample implementation500 relating toexample process400 shown inFIG. 4.FIGS. 5A-5C show an example of configuring a coverage enhancement mode for a wireless device.
• As shown inFIG. 5A,base station210 receives alocation report510 from wireless device205 (e.g., a location sensor). For example, based onwireless device205 performing a location determination,wireless device205 may transmit information associated with the location determination (e.g., a single packet encapsulating location report510) to a destination device viabase station210. As shown byreference number520, after transmitting the packet,network device230 detects a trigger to configure a coverage enhancement mode. For example,network device230 may receive information indicating that a threshold quantity ofwireless devices205 are connected tobase station210, which may triggernetwork device230 to configure the coverage enhancement mode.
• As shown inFIG. 5B, and byreference number530, based on detecting the trigger to configure the coverage enhancement mode,network device230 transmits a network measurement request towireless device205. The network measurement request causeswireless device205 to perform a signal strength measurement. As shown byreference number540,network device230 receives, fromwireless device205, information indicating thatwireless device205 measured a relatively poor signal strength frombase station210.
• As shown inFIG. 5C, and byreference number550,network device230 determines a level of coverage enhancement based on the network measurement. For example, based on receiving information indicating thatwireless device205 has relatively poor signal strength, and based on a quantity ofwireless devices205 connected tobase station210,network device230 may determine thatwireless device205 is to utilize a relatively high level of coverage enhancement (e.g., assigning wireless device205 a coverage enhancement parameter value of 3/3 on a particular scale). As shown byreference560,network device230 transmits, towireless device205, information indicating thatwireless device205 is to utilize the relatively high level of coverage enhancement. As shown byreference number570, based onwireless device205 implementing a relatively high level of coverage enhancement,wireless device205 transmits multiple copies of alocation report570, thereby reducing a likelihood that the location report will fail to be received bybase station210.
• As indicated above,FIGS. 5A-5C are provided merely as an example. Other examples are possible and may differ from what was described with regard toFIGS. 5A-5C.
• FIGS. 6A-6C are diagrams of anexample implementation600 relating toexample process400 shown inFIG. 4.FIGS. 6A-6C show an example of configuring a coverage enhancement mode for awireless device205.
• As shown inFIG. 6A,base station210 receives multiple copies of location report610 (e.g., one or more packets) fromwireless device205. As shown byreference number620, afterlocation report610 is transmitted,network device230 detects a trigger to configure a coverage enhancement mode, such as by determining that a level of network traffic satisfies a threshold, determining that an RSRP measurement associated with the network satisfies an RSRP measurement threshold, or the like.
• As shown inFIG. 6B, and byreference number630, based on detecting the trigger to configure the coverage enhancement mode,network device230 transmits a subscriber information request, regardingwireless device205, toHSS235. The subscriber information request may include information identifying wireless device205 (e.g., Device AAA123) and a user identifier (e.g., J. Doe) associated withwireless device205. As shown byreference number640,network device230 receives information identifying the class of service for wireless device205 (e.g., a class of service of silver on a particular scale indicating a relatively low class of service). As shown byreference number650,network device230 determines information identifying one or more other metrics regarding the network, such as a quantity ofwireless devices205 utilizing the network, a signal quality associated with the network, a set of classes of service for a set ofother wireless device205, or the like.
• As shown inFIG. 6C, and byreference number660,network device230 determines a level of coverage enhancement based on the class of service and the one or more other metrics regarding the network. For example, based on receiving information indicating that the class of service associated withwireless device205 is relatively low and based on the one or more other metrics indicating that an amount of network traffic satisfies a threshold,network device230 may determine thatwireless device205 is to utilize a relatively low level of coverage enhancement. As shown byreference670,network device230 transmits an instruction towireless device205 indicating thatwireless device205 is to utilize the relatively low level of coverage enhancement.
• As further shown inFIG. 6C, based onwireless device205 implementing a relatively low level of coverage enhancement,wireless device205 transmits fewer copies oflocation report680 relative to a quantity of copies oflocation report570 provided bywireless device205 when utilizing a relatively high level of coverage enhancement, as shown inFIG. 5C. In this way,network device230 reduces an amount of network congestion relative to permittingwireless device205 to utilize a higher level of coverage enhancement, thereby improving network performance.
• As indicated above,FIGS. 6A-6C are provided merely as an example. Other examples are possible and may differ from what was described with regard toFIGS. 6A-6C.
• In this way, by centralizing the level of coverage enhancement for one or morewireless devices205 rather than permitting the one or morewireless devices205 to perform a distributed determination of the level of coverage enhancement,network device230 improves the management of network traffic. Moreover,wireless device205 reduces a likelihood of excess network congestion being caused and/or excess processing resources ofbase station210 being utilized relative to permitting one or morewireless devices205 to determine the level of coverage enhancement. Furthermore,network device230 permits network resources to be allocated to one or morewireless devices205 in the coverage area based on a prioritization of one or morewireless devices205, thereby improving network performance, wireless device performance, user experience, or the like relative to another technique for determining a level of coverage enhancement that does not account for the prioritization of one or morewireless devices205.
